IMPROVEMENT INYMACHINES FOR MAKENG CIGAR-Mews.

Specification forming part of Letters Patent No. 126,957, dated May 21-,1872.

I, MORITZ H. HEIMERDINGER, of the city and State of New York, haveinvented an Improvement in Machines for Making Cigar- Molds, of whichthe following, is a specification:

Cigar-molds are made in two parts, and are grooved transversely, so thatthey come together like the teeth or cogs of .two racks, the face ofeach tooth in the upper part, and the spaces between the teeth in thelower part,

being grooved to correspond to the shape of a clgar.

My machine is composed, first, of the cutting mechanism, which consistsof a'row of cutters mounted in a substantial frame; and, secondly, ofthe feeding mechanism, by means of which a wooden blank isfirmly heldand fed up to the revolving cutters by a compound motion,.under theoperation of devices which control the direction and shape of thegrooves or cavities as they are being out, both as to their depth and asto their width.

The feeding mechanism includes an especial feature of adjustability, bymeans of which the carriage which holds the blank can be shiftedlongitudinally, so that after one set of grooves have been cut in theblank, another set can be cut in the intermediate spaces between thegrooves of the first set.

Both the cutting mechanism and the feeding mechanism contain a'varietyof features of adjustability, which are important and essential to thepractical usefulness of the machine, and which I shall presentlydescribe in detail. 7

Inthe drawing, where the same parts appear in different figures, theyare indicated by similar letters of reference.

Sheet No. 1 represents the front elevation of the machine; Sheet No. 2,a top view or plan; SheetNo. 3, Figure 1, a side elevation, and Fig. 2,a vertical section through line 22, Sheet No. 2 Sheet No. 4, Fig. 1,horizontal section through lines a: :0, Figs. 1 and 3 and Fig. 2,vertical section through line y y, Sheet Ho. 1.

A is the frame of the machine, and a a a and a are horizontalcross-pieces, supporting the cutters and the revolving mandrels, towhich the cutters are attached.

Only two cutters, &c., are shown in the model and drawing, the othersbeing duplicates of them in all respects.

The mandrels b have their journals in the cross-piecesoafiandlafi an lare each driven by belts on the pulleys b and are stayed up by theset-screws I) in the cross-piece a Each mandrel has, at its upper end, acollar, b, which is bored out to receive the stem of the cutter c. Theupper end of the cutterstem is received in the hollow plug 0 in theupper cross-piece a. The upper cross-piece a is secured to the uprightsa by the screws 0, and the holes 0 through which the screws 6 pass, areslotted, so that the cross-piece a can be adjusted to different levels,according to the length of the cutters which may be used in the machine.

As cigars vary in size and shape, different sets of cutters are requiredfor the diiferent styles of cigars. These cutters have the taperingshape of a cigar, and their peripheries are each grooved lengthwise, soas to make several cutting-edges extending spirally from end to end.

The feeding mechanism, &c., consists of the sliding bed f, which iscontrolled by the action upon the fixed screwbolt for the revolving nutf to which motion is imparted by means of the bevel-gear from thecounter-shaft f, on the outer end of which is a balance-wheel f, towhich the handle f is attached. The screwbolt f is provided with twopairs of jam-nuts, g g, for the purpose of limiting and controlling theextent of its movement in either direction. To the center of the frontedge of the sliding bed f is affixed a substantial vertical pillar, h,to which the screw-bolt f is secured. In front of the pillar h is avertical face-plate, i, extending along the greater portion of the frontedge of the sliding bed f, and permanently secured thereto. The upperend of the pillar h fits ina slot in the steadying piece 7!), which isbolted to the cross-piece a. In front of the face-plate i is another, j,of the same size, which is secured to the face-plate 2' by the screws jj. The holes for these screws in the face-plate i are slottedvertically, as shown in Fig. 2, Sheet No. 4, so that the plate j may beadjusted to different elevations, which is ef fected by means of thescrew j in the projecting cap j, on the top of the pillar h. The.

plate jhas a tongue extending horizontally along the middle, and whichfits in a corresponding groove in the sliding plate k, which is securedin position by the screws k 70 The holes for these screws in theplatest' andj are made large to allow of slight longitudinal movement ofthe sliding plate k, and the holes for these screws in the fixed plate2' are also slotted vertically for adjustment of the plate j, &c. Thesliding plate 70 has a dovetailed groove, which receives a correspondingtongue on the slide-carriage m. This carriage has a projecting flange onits lower edge, and a corresponding clamp, 0, above, which is secured tothe carriage m by screws in vertically-slotted holes, and is adjusted bymeans of the screw 0 The wooden blanks which are to be operated uponrest upon the lower flange of the carriage m, and are held firmly by theclamp 0. The sliding plate It has affixed to it at one end a slottedformer, 7.1 embracing the adjustable guide-piece, 70 The former k isheld at pleasure against either side of the guide 70 by means of theupright lever 7c, operated through the link k by the hand-lever h Theobject of the former and guide-piece is to regulate the direction of theblank in approaching and receding from the cutters, so that the cavitiesin the blank may be cut tapering in depth, and at the same time to fixboth the depth and the position of the cavities in the blank, the devicebeing so arranged that when the proper depth is reached the stationaryguide 70 exactly fills the end of the tapering slot in the former Id.The carriage m is shifted longitudinally by means of the sway-bar m andthe proper positions for the swaybar are determined by the .stop m Whilethe sway-bar m stands on one side of the stop m one series of cavitiesare cut in the blank, and when the sway-bar is moved to the oppositeside of the stop m the carriage is shifted so as to present to the toolsthe intermediate spaces between these cavities, so that another set ofcavities can be out. The cavities or grooves in the mold-boards are toonear together to be conveniently cut all at once by one series ofcutters; and I am enabled to avoid crowding the cutters together by mydevice for shifting the blank so as to cut the grooves alternately, asdescribed.

The operation of my machine is as follows: The guide-piece k is adjustedto the proper point, according to the depth required for the groovesabout to be cut, and the jam-nuts g are correspondingly fixed on thebolt j ?-that is, so that when the full depth of cut is reached theguide-pieces will exactly fill the taper end of the slot in the formerId, and the pair of jam-nuts on the outer end of the bolt f will bearagainstthe outer end of the revolving nut f so as to stop the furtherinward movement of the bolt, and therefore of the bed, carriage, &c.Having clamped a wooden blank in the carriage, motion is imparted to thecounter-shaft f so as to feed the blank up to the rotating cutters, andat the same time pressure is exerted upon the lever k so as to hold theformer against the side of the guide-piece k WVhen the grooves have beencut to the full depth, the motion of the counter shaft f is reversed,and the lever k pressed in the contrary direction, so as to hold theformer-slot against the opposite side of the guide k By this meansgrooves are out upon the surface of the blank, but gradually narrowingas they deepen, and at the bottom conforming exactly to the size andshape of the cutters.

The width of the grooves is determined by the former and guide, and, ofcourse, may be varied at pleasure by changes in the shape of theformer-slot and guide.

In the manufacture of cigar-molds it is desirable, both for economy andas a matter of.

convenience in their use, that the grooves should be as near together asthe strength of the wood will allow; and it is important that thegrooves should have inclined sides, so that the mold-boards when in usemay be readily detached from each other. I therefore determine the shapeof the former, &c., with reference to these considerations.

I am aware that rotating cylindrical cutters for shaping the grooves incigar-molds have been used; but the machines for this purpose, asheretofore constructed, have only one cutter, and are not provided withthe compound feeding mechanism and the adjusting devices, which I havedescribed, by the aid of which I am enabled to multiply the number ofcutters and operate them simultaneously, so as to greatly increase therapidity with which a series of grooves can be out, and correspondinglyreduce the cost of the molds.

I claim as my invention, and desire to secure by Letters Patent 1. Thecombination of a series of rotating cutters, c, the sliding bed f, andcarriage m, having the compound motion described, with the adjustabledevices 9 g, and former k to arrest the movement of the carriage towardthe cutters for the purpose of governing the depth of the grooves madeby the cutters, substantially as described.

2. The combination of the feeding mechanism, consisting of the slidingbed f. and the device for moving it to and from the cutters, theface-plate t, the vertically-adjustable plate j, the sliding plate 70,former k guide W, and mechanism for operating the carriage m, providedwith the clamping device '0, the swaybar m and stop m with a series ofduplicate rotating cutters, all substantially as shown and described.
